I think it depends on what youre asking for. Some search engines, not always AI but sometimes, I ask it really quick questions and I get answers. There may be calculators, conversation tools, etc already in the search.

I.e. what is 42 days from today. What's the release date of X game, etc.

I haven't had the time to switch to kagi yet but I have DDG and was just too lazy to turn off their AI feature. Didnt really bother me one way it the other. If the AI search doesnt answer my question I just move onto normal links. Again, for simple inquiries it just spits out the answers for me without having to click anything.

Believe me they're hard at work trying to fix that. I'm hoping it takes them a long time but I don't count on it.
